For the Polynomial, List Each Real Zero and Its Multiplicity $$f ( x ) = 4 ( x - 3 ) ( x + 7 ) ^ { 4 }$$

Multiple Choice

For the polynomial, list each real zero and its multiplicity. Determine whether the graph crosses or touches the x-axis at
each x -intercept.
- $$f ( x ) = 4 ( x - 3 ) ( x + 7 ) ^ { 4 }$$

A) 3, multiplicity 1, crosses x-axis; -7, multiplicity 4, touches x-axis
B) -3, multiplicity 1, touches x-axis; 7, multiplicity 4, crosses x-axis
C) -3, multiplicity 1, crosses x-axis; 7, multiplicity 4, touches x-axis
D) 3, multiplicity 1, touches x-axis; -7, multiplicity 4, crosses x-axis
